Q. If an application name is changes frequently i.e while recording it has name “Window1” and then while running its “Windows2” in this case how does QTP handles?

A.  QTP handles those situations using “Regular Expressions”.
Q. What is Parameterizing Tests?
A. When you test your application, you may want to check how it performs the same operations with multiple sets of data. For example, suppose you want to check how your application responds to ten separate sets of data. You could record ten separate tests, each with its own set of data. Alternatively, you can create a parameterized test that runs ten times: each time the test runs, it uses a different set of data.
Q. What is test object model in QTP ?
A) The test object model is a large set of object types or classes that QuickTest
uses to represent the objects in your application. Each test object class has a
list of properties that can uniquely identify objects of that class and a set of
relevant methods that QuickTest can record for it.
A test object is an object that QuickTest creates in the test or component to
represent the actual object in your application. QuickTest stores information
about the object that will help it identify and check the object during the
run session.
A run-time object is the actual object in your Web site or application on
which methods are performed during the run session.
When you perform an operation on your application while recording,
➤ identifies the QuickTest test object class that represents the object on which
you performed the operation and creates the appropriate test object
➤ reads the current value of the object’s properties in your application and
stores the list of properties and values with the test object
➤ chooses a unique name for the object, generally using the value of one of its
prominent properties
➤ records the operation that you performed on the object using the
appropriate QuickTest test object method
For example, suppose you click on a Find button with the following HTML
source code:
<INPUT TYPE="submit" NAME="Find" VALUE="Find">
QuickTest identifies the object that you clicked as a WebButton test object.
It creates a WebButton object with the name Find, and records the following
properties and values for the Find WebButton:
It also records that you performed a Click method on the WebButton.
QuickTest displays your step in the Keyword View like this:
QuickTest displays your step in the Expert View like this:
Browser("Mercury Interactive").Page("Mercury Interactive").
Q. What is Object Spy in QTP?
A. Using the Object Spy, you can view the properties of any object in an open application. You use the Object Spy pointer to point to an object. The Object Spy displays the selected object’s hierarchy tree and its properties and values in the Properties tab of the Object Spy dialog box.
